The city

by Robert Ezra Park

"The City" by Robert E. Park, E. W. Burgess, and Roderick Duncan McKenzie is a book published in 1925. This foundational work of the Chicago School of Sociology presents a revolutionary theory: cities function like natural environments, governed by competition for scarce resources. Through intensive research on Chicago, the authors developed the concentric ring theory, proposing that urban spaces divide into distinctive ecological zones shaped by social pressures and economic forces. Their model sought to explain spatial patterns and social problems in modern American cities.
